Disclaimers
Using a clutch kit with an unsprung clutch disc on a stock or lightly modified power engine that is daily/street driven vehicle can break the rivets on the clutch disc hub.

Indestructible
Color: Green, Pattern Name: Multi Color
Ordered these on a sale..I thought there were 4 bones, but only 2...I have 2 American bullies and 2 Micro bullies..All heavy chewers..These work perfectly for them and they love them...I actually had to order another pack full price so that there was 1 for each dog. Happy with my purchase, happier with the sale price but all 4 like them and can't destroy them so it's a good purchase.

My Pup Said No Thank You
Color: Green, Pattern Name: Multi Color, Color: Green, Pattern Name: Multi Color
⭐☆☆☆☆ My dog usually loves toys like this, so I was excited about them—especially since the colors were fun and it came as a pack of two. Unfortunately, my dog didn’t like these at all and kept choosing her older chew toys instead. They just didn’t hold her interest, which was disappointing. Overall, not worth the money for us.

Update after a week of having this toy
Color: Green, Pattern Name: Multi Color
I thought these were going to be more like a hard rubber but they are a very hard plastic. Keeps my dog busy but best to be supervised while chewing on it. I don’t let her have it when I’m not around so she doesn’t damage her teeth. *UPDATE* The dogs are absolutely obsessed with these toys. I was worried at first it was going to hurt their teeth and gums but they don’t. These have been a great addition to their millions of toys lol. Very happy with my purchase

Very sturdy chew toy
Color: Bacon
My Frenchy loves it! He’s not a large dog, but big for a French Bulldog. (32 lbs). He chews both ends, but prefers the snout. The eyes are cute, but began to peel off within the first week. I easily removed what was peeling. Half of the paint remained intact. When necessary, I will definitely replace it with the same toy.

Great chew toy, long lasting
Color: Bacon
This chew toy has been amazing. We have had it for 2 months with 2 dogs chewy on it and it is still going strong. We have a large Golden who chews on everything and and German Shepherd. Big dogs who chew aggressively. Very impressed! Would definitely buy again!
